RESEARCH INTEREST

The lithium-air system captured worldwide attention in 2009 as a possible battery for electric vehicle propulsion applications. Li–air battery comprises a Li-containing anode, an electrolyte and an air cathode. Electrochemical power sources based on [anode^metal|electrolyte|cathode^oxygen] configuration have the highest energy density because the cathode active material (oxygen) is not stored in the battery, but can be accessed from the environment. There is a good reason to give a proper attention to lithium as an anode material for metal/air battery on the ground of an outstanding specific capacity of its anode material (3842 mAhg⁻¹). Substantial Li-air cell performance limitations are related to the air cathode. My work is to develop air cathodes with hierarchical, several levels pore structure, which will maintain adequate transport of oxygen and Li⁺ toward the active, electron-conducting surfaces.
